When I first
started to get into 15mm modern figures there was no one place to go to
look at the ranges side by side and see if they fit well together. I
found three manufacturers so far that have good 15mm ranges. They are peter pig, Cannon Fodder minis and QRF. Let me skip
to the punch line real quick and just say all three ranges are
size-wise compatible with each other, and have enough variation that
you can put together a real nice force between them. All
three sell their packs with multiple poses.

Peter Pig

I buy my Peter Pig guys from Brookhurst Hobbies. These
guys have great service and any time I've ordered from them it has been
at my doorstep in well under a week. Peter Pig has no modern US range
per se. However they sell heads with fritz helmets, fritz helmets with
goggles as well as other types. This leads to the simple conversion of
twisting off the old head from the mini and with a little drill and
xacto knife replacing it with a new hood. this is nice since you have
the heads looking in different locations which individualizes all your
guys. For the actual figures I mostly use the IDF range. They have a
line of IDF w/M16 which works great as does all their guys. The figures
are easy to work with and well detailed with kit radios etc.. I also
used some of their Vietnam range, in particular M60 gunners and
Snipers. (I use the IDF LMG for M249 SAW guys and teh M60s for M240b
guys.) Between all the options in the IDF range you could really stop
right there. NOte: You don't get any 203s! (Though there are M79s in
vietnam range. Anyways you can make 203s easy enough from scratch) One
note about Peter Pig figures: The guys have their sleeves rolled up,
which you don't really do these days. (Just a caveat for the stickler
types.)

rest from their IDF range

As far as enemies go, Peter Pig has
a whole PLO range. Between these and their African militia range (which
can double as Somlais or just plain clothes enemies, you really have a
nice mix of options. They also carry some nice vehicles especially the
Toyota "technical". And if you've ever been in the region (Gulf) you'd
know that it seems almost everyone drives a white toyota pick up
over
there!.

a nice range of civilians, casualties reporters and other incidentals.
Included in this pic is a dead guy from the Cannon Fodder afghan range.

Cannon Fodder
Miniatures

Cannon Fodder make s nice range of
modern wars figures, to include SF guys, Rangers African and Afgan
militias. They are a tad lighter and a microbit taller than peter pigs
but hardly noticeable and are kitted out with M4s carrying all the
latest attachments as well as knee pads, some of the rangers have holes
drilled in their helmets for I presume, night vision goggles but these
didn't come with the packs and I didn't see how to order them
separately though they are easy enough to make from scratch.

The shining star of Cannon Fodder
minis IMO are their great Afgans. These guys have many great poses.
They even make Osama! Be careful not to drop him on the carpet as he's
notoriously hard to find.

QRF
QRF Makes a wide range of modern vehicles and minis. These guys are a
little heftier and less well sculpted. The US guys are all carrying
large Molle packs. However they have some good poses and fit in great
with the rest of the figures. And they paint up nice and with a black
wash the detail comes out in the packs. I also like their Special
Forces guys. Note on the radioman alone I will probably cut down
that antenna as it's too thick and leave a smaller antenna. then it'll
look like the LOS antenna on a satcom. There's no goggles on
these guys but some of the figures were amenable to new heads form
peter pig(see the RTO below.)

Here are the three ranges standing together for side by side
comparison: Cannon Fodder-Peter Pig-QRF.

Vehicles
Honestly the first thing to do is peruse your local toy store. Matchbox
used to make a range of bradleys that went for like ninety nine cents
which are great for 15mm with a repaint. The matchbox M1A1s are too
small but the Johhny Lightning M1s are perfect 1/100 scale and cheaper
already painted by half than QRF white metal M1s. I filled out the
holes in my range from QRF with Hummers (M2 and Mk19), little birds and
LAVs . (No Strykers around yet.) While there are UH60s out there in
1/100 they're hard to find. Believe it or not I found some UH60 pencil
sharpners die casts on ebay which work great! In all you can't go wrong
with the quality and variety of the QRF vehicle range.
